Abstract

This paper presents a new solution for filtering current
harmonics in three-phase four-wire networks. The original
four-branch star (FBS) filter topology presented in this paper is
characterized by a particular layout of single-phase inductances
and capacitors, without using any transformer or special electromagnetic
device. Via this layout, a power filter, with two different
and simultaneous resonance frequencies and sequences, is
achieved—one frequency for positive-/negative-sequence and another
one for zero-sequence components.

This paper presents the analysis of shunt active
filter (SAF) in harmonic damping. SAF with voltage-based
detection control act as an active damping and able to
attenuate harmonic propagation throughout the power
distribution ...
